Well, everything mentioned was from the ROTK EE DVD, which I have refused to watch...I've seen all the special features, but not the actual movie because I'd heard multiple places that it just wasn't as good as the theatrical release, which I loved (in spite of it not completely matching the book, it is my absolute favorite of the three). So I didn't watch that one. But I have seen FOTR and TTT...so allow me to contribute my least favorite scene from the TTT EE, since I loved the FOTR version.
I didn't like the construction and flow of the TTT EE as a whole, especially towards the end, but one moment just stuck out in particular as especially bad.
It's the scene where Legolas and Gimli are arguing about their final tallies, and Gimli delivers his (in)famous "nervous system" line, in a weak attempt at humor. It was laughable, but didn't have the effect they were going for...and got a cringe from me, instead of a laugh. It just completely jarred me out of Middle-earth. I'm assuming that was the reason why it was left out of the theatrical release, and I just don't see what was gained by putting it into the EE at all.
